T Decoder with BEMF (Back Electro Motive Force, aka load compensation)

T Suitable for use with any DCC system or DC (dual mode decoder) *)

T Superb low speed operation. Maintains a constant speed despite any track grades.

T 3 Function outputs and Shunting mode available.

*) Some DCC systems allow you to use ONE locomotive without decoder using the DCC „stretched zero-bit“ option. If you plan to useLokPilot Basic decoders, you can‘t use this option, as it disturbes the LokPilot Basic. Every engine on your layout must have a decoderinstalled.

Important warning:• Don‘t expose to wet and humid conditions and

avoid mechanical force or pressure on thedecoder

• Do not remove the heat shrink sleeve• Never solder on the decoder, extend cables if nec-

cessary• Never wrap the decoder in insulation tape, since

this may cause overheating• Always disconnect the circuit when installing the

decoder• Make sure that no wires are squeezed or cut when

reassembling the engine

Installation requirementsThe engine must be in good mechanical condition: Onlyan engine running smoothly in analogue mode should bemodified for digital operation. Check and replace anywear and tear parts such as motor brushes, lamps etc.

InstallationLokPilot Basic is possibly supplied with an NMRA DCC 8-pin plug (Figure 1): Insert the decoder plug with pin 1 (theside with the red/orange wire) into the side of the socketthat it usually marked with *****, +++++, • or 11111.Engines without interface: Disconnect any existing wi-

res within the locomotive and any connection to thechassis. Both motor contacts must be insulated, makesure there isn‘t any connection to the chassis or thewheels. The exact connection is shown in figure 2. Con-nect the second pole of the function outputs (the bluewires) to the blue wire. The blue wire must not be con-nected to the chassis!Engines with 21MTC Interface: Simply plug in the deco-der into the socket. Note the index pin to avoid wronginstallation

Function outputsAny load may be connected to the light and functionoutputs as long as it doesn’t exceed the maximum cur-rent. Avoid short circuits. Although the output circuitsare protected, a high voltage on the terminals or a shortcircuit may cause damage. Use only 16 V bulbs or higherand a maximum nominal current of 50 mA.

DCC operationLokPilot Basic may be operated with any DCC compatib-le system, as long as every engines is decoder fitted.

make sure the speed step settings of both your DCC sys-tem and the decoder do match: As the decoder is pre-setto 28 speed steps, the throttle must have the same set-tings, as otherwise the headlights will blink at each changeof speed steps. You can re-program the decoder to 14speed steps using CV 29.

Programming of the decoderA comprehensive list of all supported CVs can be foundbelow. There is no „one fits all“ instruction for program-ming CVs with various DCC systems. Please refer to yourDCC system‘s manual for instructions. LokPilot Basicsupports all DCC programming modes.
